Off the clock
QNH that is.
Not flying, but setting up an instrument panel and the altimeter was off the scale with the current pressure setting - 1037 HPa. The sub-scale stopped at 1035 though it did allow further adjustment beyond that.
This is a new certified sensitive altimeter with JAR form 1 (Winter).
I can't recall ever being off the top of the scale before and checking an old altimeter, the subscale on that goes up to 1050.
Does anyone know typically how often we get this high a pressure in the UK?
Is it common to have this limited a sub-scale?
